Bush did not dress for practice and was off to the side doing running exercises Wednesday, just as he had most the season while on the Reserve/Non-Football Injury list.

He practiced with the team the past three weeks. The team had to decide by 1 p.m. today whether to add him to the 53-man roster or put him on the IR. Since he wasn’t in uniform, they seem to have taken the IR route, though they can also put him back on the Reserve/Non-Football Injury list.

Either way, Bush won’t get to test his healed right leg this season — he broke it the first game of his senior season at Louisville, and the Raiders drafted him in the fourth round of April’s draft knowing he had recovery time ahead of him.

Since Jordan appears stuck on the roster despite asking for his release Monday, it will be interesting to see how Raiders coach Lane Kiffin handles the former starter. Jordan hasn’t played in two games and was put on the inactive list Sunday.

In other practice news:

Left guard Robert Gallery was seen taking snaps at right tackle, a position he played as a rookie in 2004-05. He could be getting ready to replace Cornell Green, who has an ankle injury.

No word on who would replace Gallery at left guard. Former center Jake Grove is one option, but he’s been limited by a knee injury recently and was not seen on the field at the start of practice.
